A friend of mine expressed some frustration she was having while making some flower girl dresses and how the bias tape at the fabric store just wasn't the right color she was looking for. She then decided to make her own! HA! I had never thought of that before, so I went to work attempting to figure it out. Here's a tutorial if you're ever in need of "matching bias tape" and the fabric store doesn't have what you want.
Step 1: You need to "square" your fabric so it can be cut on the bias. To do that, just take one of your corners and fold the fabric down along the opposite edge to create a triangle (just like folding a rectangular piece of paper into a square). Don't just cut strips off the rectangle, or it won't "stretch" like bias tape.
Step 2: Using a rotary cutter and ruler, measure the strips for cutting. I wanted the bias tape to be about 1/2" wide, so I cut my strips 2" wide to allow for the folds.
**Note** The bottom, longest strip has a folded edge along the bottom, so just open the fold and cut it apart.
